- the method comprising a step of receiving at the remote object detection unit a reflected electromagnetic signal.
- the method comprising a step of determining whether a remote object is present based on the reflected electromagnetic signal and the relative direction to the remote object.
- the steps of transmitting and receiving may be performed iteratively so as to sweep a number of sections iteratively or according to a schedule or scheme.
- a third aspect relates to a system, where a head-worn apparatus and a remotely worn device are in wireless communication.
- One or both of the apparatuses/devices of the system may comprise an antenna having adaptable directionality for transmission and/or reception of wireless signals.
- the directionality of the antenna may be adapted based on information on where the recipient and/or transmitting device is placed relative to the other device.
- the adaptation of the antenna may lower the risk of interfering signals reducing the link quality.
- the two devices of the system may exchange information on the relative direction to the other device so that the directionality of the antenna may be even faster adapted to establish a good wireless link between the two devices.
- the direction from one device of the system towards the other may be determined using an remote object detection unit transmitting an electromagnetic signal as outlined elsewhere in the present specification.
- Such a system may comprise a head-worn apparatus for enhancing sound perception of a first user and a remotely positioned device configured to be in wireless communication with the head-worn apparatus and to be positioned at a second user.
- the head-worn apparatus may have a housing adapted or configred to be worn at the head of the user, and an antenna configured to receive a wireless signal from the remotely positioned device, and an output transducer to provide a signal perceived as sound by the second user.
- the remotely positioned device may comprise a microphone system configured to receive ambient sound, and a direction determination system configured to determine a desired direction.
- an antenna having adaptable directionality may be included, further included may be a processor for adapting the adaptable directionality of the antenna based on the desired direction, and the processor may then be configured to transmit, via the antenna, a signal based on the ambient sound received via the microphone.
- the antenna may have a relatively narrow beam, which may then be adapted to be directed towards the other device during use.
- An initial direction may be obtain, e.g. via a scan for an optimal link direction using the antenna to e.g. sweep through a number of directions.
- One of the devices may e.g. be configured to transmit a beacon signal during acquisition or determination of the link direction.
- the two devices may be configured to exchange information on e.g. link quality, such as signal-to-noise measures, packet loss information, or other quality measures/indicators.
- At least one of the devices comprise an adaptive antenna so that the transmit and/or receive direction may be adapted.
- both devices may include an antenna with adaptable or configurable directionalities. If even further devices or apparatuses are part of the system, e.g. multiple students each having at least one hearing aid, each of the devices or apparatuses may include such an antenna having adaptable directionality.
- a person may wear two hearing aids, often referred to as a binaural hearing aid system, where each ear is fitted with a respective hearing aid.
- the hearing aids need not be of the same type.
- a person may e.g. have a hearing aid providing air born sound to one ear, and e.g. a bone-conducting hearing aid at the other ear, or even an implanted system.
- a desired direction may be determined from at least the device having an antenna with adaptable directionality. This could be achieved e.g. by performing a sweep with antenna so as to emit a signal, such as a beacon signal, or correspondingly receive such a signal.
- a sensor may provided information on movement of the person carrying the respective device. This could for instance be an accelerometer indicating that the head of the user is turned, tilted or moved in another way. This additional information could help keeping the directionality of the antenna in an optimal direction.
- the antenna having adaptable directionality may have a number of discrete directions that the antenna is able to receive and/or transmit.
- the antenna having adaptable directionality may have angular limits between which the directionality is definable.
- the antenna having adaptable directionality may be adaptable both in vertical and/or horizontal directions relative to the wearer.
- the embodiments of the disclosure preferably seeks to mitigate, alleviate or eliminate one or more of the above mentioned disadvantages singly or in any combination.
- the method according to the second aspect may also be used for aiding a blind-source separation algorithm as detecting the presence of an object may help the algorithm to more quickly separate sources.
- the method as disclosed may be embodied in a computer program product being adapted to enable a computerized system comprising at least one apparatus having data storage means in connection therewith to control a remote object detection unit in an apparatus according to the first aspect of the disclosure.
- Fig. 1 schematically illustrates an apparatus 10 having a housing.
- the apparatus is positioned at an ear of a person and comprises two parts or housings. One housing is positioned behind the ear, and one housing is positioned at the ear canal or ear canal opening. The two parts or housings are connected by connector.
- the apparatus illustrated is a hearing aid, but the functionality described herein could also be used in a hand-held microphone, or even in a stationary device, e.g. a conference telephone or device connected to e.g. a TV.
- the apparatus 10 comprises a directional microphone system in the housing, which directional microphone system has adaptable directionality.
- This directional microphone system could for instance be established using two, three or even more, omnidirectional microphones positioned spaced apart by a known distances. By using combinations of the signals from two, three more microphones allows establishment of a directional microphone system. This combination could include delay and/or phase-shift of the signal.
- the apparatus 10 further comprises a processor for adapting the adaptable directionality of the directional microphone system. This processor performs the needed adaptation of the directionality.
- the adaptation may include acoustic processing for identifying sound sources. Often hearing aids are equipped with directional microphone system so that sound is picked up from a preferred direction, such as substantially from in front of a person using the hearing aid.
- Sound processing algorithms may be used to track the relative movement of a sound source identified via the directional microphone system.
- a remote object detection unit may be employed.
- the remote object detection unit is configured to detect a remote object, such as a person or an inanimate object, by detecting a transmitted signal which has been reflected from the object. This operation is similar to the operation of a maritime 3 or 10 cm radar; however, at e.g. 79 GHz the wavelength is suitable for small formfactor, low-power modules, which may be incorporated in housings to be worn at an ear of a person or held in the hand. Such devices may be incorporated in a 28nm CMOS RFIC design.
- the processor is then adapted to direct the directionality of the directional microphone system based on the detection of the remote object.
- the remote object detection unit detects may be set up to sweep a certain angle interval relative to the housing.
- the remote object detection unit may be configured to sweep an area or angle at certain intervals.
- the remote object detection unit may be setup for detecting objects according to previously detected object, e.g. if one object has been identified recently, a scheme for sweeping may be adapted accordingly. This scheme could be aimed at detecting new sound sources and/or to maintain the direction of the directional microphone system pointed at the sound source, which may be shifted due to head movements and/or the sound source moving.
- This scheme could be aimed at detecting new sound sources and/or to maintain the direction of the directional microphone system pointed at the sound source, which may be shifted due to head movements and/or the sound source moving.
- the remote object detection unit may be used to keep track of possible sound sources, and the directional microphone system and the accompanying audio processing algorithms, may then be used to point out the desired sound target from the identified possible sound sources. This may alleviate the sound processing as less time and processing is used to identify active sound targets.
- the remote object detection unit may be configured to transmit, and receive, an electromagnetic signal having a carrier frequency within the 1 to 100 GHz frequency range.
- this remote object detection unit When this remote object detection unit is included in a housing carried by a person, it is possible to determine the speed of a detected remote object, or at least the relative speed of the detected remote object. This could be done using the Doppler effect, which also provides information on the relative movement of the remote object, i.e. closing in or moving away. The determined speed, possibly along with the direction, could be used to determine if imminent danger of collision. This could be advantageous when the user is moving around in a busy environment, such as a city centre with cars, busses, trucks, bicycles and people. A speaker unit could then provide an acoustic signal upon detection of a remote object having a speed above a given threshold, as this could indicate e.g. an approaching vehicle.
- the remote object detection unit could also be used as a proximity warning system indicating that an object is within a given distance from the user. Combinations of the properties of the remote objects may also be used, e.g. an approaching vehicle having a speed above some threshold within a given distance will cause the speaker to emit a sound. Further, a small vibrational unit may be included in the housing to provide a vibrational sensation at the ear. For binaural systems, that is system with a hearing aid at each ear, it is also possible to provide directionality the warning, so that if something is approaching from the left, a warning is given at the left ear, etc.
- the remote object detection unit Depending on the resolution level of the remote object detection unit, it is possible to characterise the remote object as one of: a person, a car, a bicycle, a fixed metallic object.
- the apparatus is described as a hearing aid but could also be a hand-held microphone, a wearable device or a stationary device.
- a stationary device could be a so-called TV-box.
- Fig. 2 schematically illustrates a head of a user where a hearing aid is placed at a right ear where a remote object detection device scans in an angle of ⁇ degrees.
- the angle ⁇ may be determined by the characteristics of the antenna used. As illustrated in Fig. 4 the angle may be larger than shown in Fig. 1 .
- Fig. 3 schematically illustrates a head of a user where a hearing aid is placed at each ear where each remote object detection device scans in an angle of ⁇ degrees.
- Fig. 4 schematically illustrates a head of a user where a hearing aid is placed at each ear where each remote object detection device scans in an angle of ⁇ degrees.
- the angular restriction could extend backwards of the head so as to allow the directional microphone system to adapt and pick up sounds emanating from behind the user, e.g. a caretaker pushing a wheel chair.
- Fig. 5 schematically illustrates a head of a user where a hearing aid is placed at each ear where each remote object detection device scans in an angle of ⁇ degrees.
- Each angular section is divided into a number of subsections.
- the subsections are illustrated as being separated, but in practice there will be some overlap due to the directionality characteristics of the antenna used for the remote object detection unit.
- the subsections may be scanned consecutively, randomly or according to a fixed scheme. Whichever method is used, the method may be adapted according to which environment the user is in.
- Fig. 6 schematically illustrates steps of a method of operating an apparatus having a directional microphone system having adaptable directionality, a processor for adapting the adaptable directionality of the directional microphone system, and a remote object detection unit configured to detect a remote object.
- the method comprises a step of transmitting from the remote object detection unit an electromagnetic signal.
- the method comprises a step of receiving at the remote object detection unit a reflected electromagnetic signal.
- the remote object detection unit thus emits a signal in a given direction and awaits an echo. This allows detecting an angular direction to the remote object, if present. Further processing and analysis of the echo may provide information on the speed of the remote object, e.g. based on the Doppler Effect.
- the directional microphone system may then provide information on whether any detected remote object is an active sound source or not. If active, the directionality of the directional microphone system may be adapted based on the detection of a remote object directional microphone system.
- the adaptation of the directionality of the directional microphone system may be conditioned on the remote object being classified as a sound source. In the cocktail scenario, one source may be identified as a preferred source and the directional microphone system may be adapted accordingly, even if more active sound sources are identified.
- a combination of the remote object detection unit and the directional microphone system may be used for identifying remote active sound sources.
- a classification of the remote object may include determining if the remote object is a human or a machine. This could be used for automatically determining if a warning signal should be issued for warning the user of an approaching vehicle.
- the remote object detection unit can be used to detect active and silent remote objects and the directionality of the directional microphone system could be used for scanning the remote objects detected by the remote object detection unit to classify them as active or silent.
- a further use of the knowledge of the direction to a source is to adapt a directional antenna, such as an array antenna comprising two or more smaller antennae elements.
- the array antenna could comprise two, three, four, five, or more elements.
- the loss of wireless link from e.g. a remote microphone will result in a loss of audio packets between the transmitting device and the receiving device, and therefore loss of audibility.
- a student wearing a hearing aid linked to a remote microphone of the teacher may have the adverse effect of the student not understanding what the teacher said.
- the antenna could be positioned at, such as under, a surface intended to face away from the teachers body.
- This part of a portable device, such as a teacher microphone could provide a surface having a relatively large area for positioning multiple antenna elements.
- an antenna could be formed at or under a side wall of the hearing aid housing that is configured to be positioned behind the ear of the user, whereas a second part is configured to be positioned in the ear canal, e.g. having a receiver and/or ear mold.
- a receiver and/or ear mold Such as configuration is, as described above, often referred to as either a receiver-in-the-ear or behind-the-ear.
- the antenna When a, relative, direction from one device towards the other, remotely placed, device is determined, the antenna may be adapted so that the signal transmitted from the antenna is directed towards the other device.
- the determination of the direction may also be used for controlling the adaptable directionality of the microphone. Further, the above-mentioned electromagnetic signal transmission system may be used as at least part of the direction determination.
- the antenna with adaptable directionality could be embodied as an antenna array, or multiple antenna arrays, with smaller radiating elements combined with signal processing and beamforming.
- the antenna array could e.g. be a line of 2, 3, 4 or more smaller antennae with switchable elements.
- the antenna array could be e.g. a square with 2x2, 3x3, 4x4 or other combinations of smaller antennae with switchable elements.
- the antenna array could be e.g. arranged as a rectangle with 2x3, 2x4, 3x4, 3x5, 4x5 or other combinations and/or permutations of smaller antennae with switchable elements.
- a phased array architecture could employ beam steering and forming using RF-phase and/or amplitude shifters, or beam forming networks.
- the adaptation of the antenna may be performed continuously, periodically or event based. Further, adaptation may, in some cases, be performed just prior, and/or during, transmission of data.
- Fig. 7 schematically illustrates two devices each having an adaptable antenna system.
- One of the device is to be worn by e.g. a teacher and the other by a student.
- one device e.g. being a hearing aid
- the other device e.g. a microphone device
- the microphone device could simply be placed on a table during a social event for improved microphone reception.
- the microphone device is to be positioned remote from e.g. the hearing aid user, which could be a, young, student in a classroom setting. As the teacher moves around, the wireless link may be disturbed, especially when the antenna is a highly directional antenna.
- a link having a high link quality e.g. expressed by a low packet loss or the like, may be established and maintained even when the source, or the device having the antenna, is moving or shifting.
- Fig. 7 this is illustrated by three antennae elements together forming an antenna array. Both devices are illustrated having the same array, however, the two, or more, devices need not implement the same type or structure.
- the head-worn apparatus may include that the device is configured to transmit the detected direction towards the remote device via the wireless to the remote device, and wherein the remote device is configured to adapt the direction of the adaptable antenna based at least in part on the relative direction from the head-worn device.
- At least one device in a system is able to include information from the other device when determining how to adapt the directionality of the adaptable antenna. This could increase the efficiency of the system and possibly lower the time needed to establish the desired direction.
- One or more devices of the system may include a positioning device configured to provide a signal representing the position of that device as e.g. a coordinate set in a global coordinate system. Having more devices of the system including such a positioning system could allow for an adaptation of the antenna based on at least two coordinate sets.
- Other direction indicators may be included, e.g from a radar system in one or more of the devices as disclosed herein.
- One or more of the devices of the system may be configured to transmit a beacon signal that another device of the system may register.
- This beacon signal may e.g. be used to determine the direction to the device emitting the beacon signal.
- the determination of the direction may e.g. be based at least in part on determining signal strength of the beacon signal. This could be achieved using an antenna having adaptable directionality.
- a hearing aid may be provided where the microphone system may be adapted based on a determined direction to a source. Further, an antenna having adaptable directionality may be adapted based on the determined direction to a wireless source. Still further, both a microphone system and an antenna may be adapted based on a determined direction to a source emitting both sound and a wireless signal.
- a teacher may carry a device with a microphone and a wireless system for broadcasting a signal based on the microphone.
- One or more students may then have each their hearing aid or aids which each include an adaptable antenna, each of which are configured to determine a direction to the teacher to establish and maintain a wireless connection to be able to receive wirelessly the signal based on the microphone.
- the system may include a stationary unit routing the wireless signal from the teacher, which stationary unit then broadcast a signal to the students respective hearing aids.
- the antenna system may be configured to search a fixed number of directions. This could e.g. be two directions where a signal strength indication is obtained from both directions and the direction having the stronger indication is then chosen. Further numbers of spots or directions may be used. In a situation where e.g. three directions are relied upon, the three directions may form a triangular geometry, seen in a direction directly towards the antenna. This could allow for optimising the directionality in situations where the transmitting antenna is located at an elevated position relative to the receiving antenna, such as a teacher standing in a classroom while the student or students are sitting down.
- the antenna is able to transmit and/or receive in allows for greater flexibility.
- inductive communication e.g. a telecoil
- inductive systems e.g. for through-the-head communication.
- the directionality pattern should favour the angle of incidence of the several hearing devices.
- Directionality could also favour the hearing devices that would otherwise have the lowest wireless communication signal-to-noise ratio.
- the method may include determining speed of remote object, and provided the speed is above a threshold, the method comprises issuing a warning signal.
- any of the disclosed embodiments may be physically, functionally and logically implemented in any suitable way such as in a single unit, in a plurality of units or as part of separate functional units. It is intended that the structural features of the devices described above, in the detailed description and in the claims may be combined with steps of the method, when appropriately substituted by a corresponding process. Embodiments of the method have the same advantages as the corresponding systems.
